To remain competitive in today’s ever-changing power generation landscape, many plants are exploring the addition or removal of a secondary fuel.
Although adding fuel sources can provide an extra revenue stream or more reliable generation capability, removing secondary fuel sources simplifies operations and can reduce long-term maintenance costs.
While more than one source of fuel enhances operability, the additional fuel system adds hardware complexity. Dual or triple fuel components are more complex and more expensive to repair than single fuel components.
Additional hardware required may consist of fuel storage, fuel handling and filtration, fuel metering and control, instrumentation, fuel distribution and the combustion system itself. The simplicity of a single fuel source and the lower cost to maintain that equipment is a significant benefit.
